The Saviors attack the Hilltop with their tainted weapons, leading to a battle in which both sides suffer heavy casualties. Tara is injured by Dwight in an effort to prevent Simon from killing her. Overnight, the injured die from their tainted wounds and attack the sleeping survivors after reanimating.
